Resolution

There are several reasons why an instance of VoiceObjects might fail to start.

• No database access.
  Make sure the database is available and you use the correct login.
• The required database tables in the metadata repository were not created or configured during the installation.
  If VoiceObjects was installed from scratch you may need to run the appropriate database scripts from the folder [VoiceObjects]/Platform/WEB-INF/driver/db/ if this hasn't been done during installation.
  It is strongly recommended to first read the relevant paragraph in the product documentation (see Chapter 5 - Subsequent Configuration in the Installation Guide).
• The existing metadata repository has not been upgraded to the new release or upgrade.
  The metadata and logging repositories need to be upgraded with the appropriate upgrade scripts located in the [VoiceObjects]/Platform/WEB-INF/driver/db..
  It is strongly recommended to first read the relevant paragraph in the product documentation (see Chapter 5 - Subsequent Configuration in the Installation Guide).
• There is no license key available in the repository or the existing license key is invalid or has expired.
  To start VoiceObjects Server a valid license key has to be provided. For details refer to Applying License Information for VoiceObjects in Chapter 5 - Subsequent Configuration in the Installation Guide.
• The computer clock or the path to the VoiceObjects installation has been changed
  This latter might happen when you create a new VoiceObjects instance by copying the /Platform/ folder of an existing instance. The message Invalid EasyLicenser configuration condition. Corrupt hidden file will be shown.
  To change this locate the (hidden) file .ezl* in the affected instances /WEB-INF/config/ folder and delete it. Then restart the instance.
• You have installed an upgrade of VoiceObjects by unzipping a package or by copying VoiceObjects folders, which will confuse the licensing system.
  The message Invalid EasyLicenser configuration condition. Corrupt hidden file will be shown.
  To fix this, locate the (hidden) file .ezl* in the affected instances /WEB-INF/config/ folder and delete it. Then restart the instance.
